LLM Broadcaster

About

LLM Broadcaster turns a dedicated browser profile into a local multi-model AI workspace.

Type one prompt once, choose the services you want, and broadcast that prompt into multiple already-open AI chat tabs. It is built for people who compare outputs across models for writing, research, coding, debugging, planning, and creative work.

The workflow stays inside your browser:

• No API keys
• No backend
• No external prompt routing
• No analytics or telemetry
• No hidden tracking

Features:

• Broadcast one prompt to multiple AI services
• Reuse existing AI tabs instead of opening duplicates
• Open missing tabs automatically
• Use built-in groups like Code, Research, and Creative
• Save custom service groups
• Save reusable prompt presets
• Keep local prompt history
• Add an optional context prefix to every broadcast
• Reset AI tabs to a fresh chat with one click
• Use the popup or persistent side panel

LLM Broadcaster does not replace the AI services themselves. You still use your own logged-in browser sessions. The extension simply helps you send the same prompt to the services you choose without repetitive copy-paste.

Recommended setup:

Use a dedicated Chrome or Brave profile for AI work, stay logged in to the services you use, and keep the extension pinned for fast access.
